Weight-for-length for girls at 105 cm

At a length of 105 cm, the median weight for girls on the WHO Child Growth Standards is 16.5 kg (36 lb 8 oz): half of girls of this length weigh less and half more. The middle half of girls, from the 25th to the 75th percentile, falls between 15.6 and 17.6 kg, a spread of 2.06 kg. The outer lines of the chart, the 2nd and 98th percentiles, sit at 13.8 and 20.0 kg.

At 103 cm the median weight is 15.9 kg, so 2 cm of extra length goes with about 0.64 kg more weight at the median. At 107 cm it is 17.2 kg. 105 cm is close to the median height of girls at 5 years (107.7 cm). Weight-for-length compares a child's weight with other children of the same length, whatever their age, which is why it can read differently from weight-for-age for a long or a short baby.

For boys at a length of 105 cm the median is 16.6 kg, 0.08 kg more than for girls, which is why the charts are drawn separately by sex.

CDC 2000 weight-for-length tables stop at 103.5 cm, so at 105 cm only the WHO standard applies.

Reading the table: a girl at a length of 105 cm who weighs 17.2 kg is at about the 66th percentile, meaning that out of 100 girls of that length, about 66 weigh less.
